The Difference Between Optical Fiber and Optical Transceiver Module
The optical fiber is a light transmission tool, composed of glass and plastics and can be used for communication transmission.
The optical transceiver module is designed to transmit between electricity and optical signal through its sending point. And through the optical fiber the receiving point would change its optical signal into electrical signal.
Data rate depends on the optical transceiver modules, and different signals are sent by the same optical fiber.
